Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Incorrect Implementation of Authentication Algorithm
EUVDB-ID: #VU25572
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-8863
CWE-ID:
CWE-303 - Incorrect Implementation of Authentication Algorithm
Exploit availability: No
Description
The vulnerability allows a remote attacker to to bypass authentication process.
The vulnerability exists due to a lack of proper implementation of the authentication algorithm within the handling of HNAP PrivateLogin login requests. A remote attacker on the local network can bypass authentication and reset the admin password.
An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router.
Install updates from vendor's website.
Vulnerable software versionsDIR-867-US: v1.10b04

CWE-ID:
CWE-697 - Incorrect Comparison
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to a lack of proper handling of empty passwords within the handling of HNAP strncmp login requests. A remote attacker on the local network can bypass authentication and reset the admin password.
An attacker can leverage this vulnerability to execute arbitrary code on the router.
